Crysis Warhead updates and refines the gameplay of the original game through a sidestory plot involving Psycho, one of previous protagonist Nomad's allies. The game is a parallel story that follows Sergeant Michael "Psycho" Sykes, a character from the original Crysis, as he faces his own trials and challenges on the other side of the island during the time period of the first game.

It also showcases a new, enhanced and optimized version of CryEngine 2 using full DX10 extensions and is the first game developed by Crytek's Budapest studio.

Under Warhead we again see that at the lower resolution performance is a bit all over the place. At the lowest the quad SLI setup is actually slower, but at 2560 x 1600 we have some impressive gains with performance in the minimum department being almost 40% faster.
